Full Ceramic Bearings have races and balls that are made entirely
of ceramic material and are superior to common steel bearings in
many ways. Ceramic is the perfect material for any application
seeking to achieve higher RPM’s, reduce overall weight or for
extremely harsh environments where high temperatures and corrosive
substances are present.

Because ceramic is a glass like surface it has an extremely low
coefficient of friction and is ideal for applications seeking to
reduce friction. Ceramic balls require less lubrication and have a
greater hardness than steel balls which will contribute to
increased bearing life. Thermal properties are better than steel
balls resulting in less heat generation at high speeds.

Ceramic bearings can have a retainer or full complement of balls,
retainer materials used are PEEk and PTFE.

Full ceramic bearings can continue to operate under extremely high
temperatures and are capable of operating up to 1800 Deg. F.
Ceramic is much lighter than steel and many bearings are 1/3 the
weight of a comparable steel bearing. Full ceramic bearings are
highly corrosion resistant and will stand up to most common acids,
they will not corrode in exposure to water or salt water. And
finally full ceramic bearings are non-conductive.

The purpose of a radial bearing is to reduce rotational friction
and support loads. This is achieved by using two races to hold the
balls and to spread the load through the balls. As the bearing race
rotates it causes the balls to rotate. The ball provides for
substantially less rolling resistance and coefficient of friction
than if two flat surfaces were rotating.

Single-row, deep groove radial ball bearings are the most common
bearing type, having a wide range of applications. Radial bearings
are made with very high levels of precision and used in
applications where rotational performance and low torque is
necessary, but load is a secondary issue. Deep-groove bearings
however do have higher load ratings for their size than
shallow-groove ball bearings, but are also less tolerant of
misalignment.

Ceramic hybrid ball bearings use ceramic balls. Ceramic balls weigh
up to 40% less than steel balls, depending on size. This reduces
centrifugal loading and skidding, so hybrid ceramic bearings can
operate up to 50% faster than conventional bearings. This means
that the outer race groove exerts less force inward against the
ball as the bearing spins. This reduction in force reduces the
friction and rolling resistance. The lighter ball allows the
bearing to spin faster, and uses less energy to maintain its speed.
Ceramic hybrid ball bearings use these ceramic balls in place of
steel balls. They are constructed with steel inner and outer rings,
but ceramic balls so they are known as hybrids.
